From this vedio, what I got to see that while at climb or takeoff, low pitch and high rpm is required for which oil goes back from propeller to oil tank.

Ah that's how they work. Very well explained. I think James Clerk-Maxwell wrote something on this subject a while ago. Kudos for the like and to those who know who James Clerk-Maxwell was. For others he wrote a paper "On governers" in 1868. It gave the mathematics behind designing governors as used with Watt's steam engine. The first paper on control. He also combined electricity and magnetism to show them as being one. Later another physicist stood on his shoulders who is today sadly much better known than Clerk-Maxwell.

Secondly, when climbing/descending, the order of using throttle lever, eg. when Climbing (adding power): Pitch first, Throttle second; when Descending (reducing power): Throttle first, Pitch second.

This is only correct for single acting non-counterweighted propellers. The Governor is not always directly driven by the crankshaft, many are driven from the accessory drive, or even the from the gun synchronizer drive, i.e. P&W 985 for one.

This is just a general intro to the basic concept. The point is, it turns a speed proportional to the engine. Any point the motion gets picked off from, is all the same result.
@waitdaniel4 жыл бұрын
great explanation, cheers. As you said the pilot increase the RPM but the plane pitched up, the governor would automatically adjust the blade angle to compensate the RPM?
@michaelgeorge30923 жыл бұрын
my understanding is yes. as pilot increases throttle, rpm goes up. gov increases pitch to bring it back down. in doing so prop has more bite, more thrust. if the pilot pulled up without increasing throttle, then prop loading will slow rpm down, causing governor to reduce pitch, allowing speed to pick up again. so rpm remains constant. caveat is prop will be at lower pitch during climb.

@Thomson_Tam4 ай бұрын
Be careful this is for single-engine aircraft. With oil pressure lowering the RPM, and nitrogen gas/spring send the PRM towards the high. So in the case of losing oil pressure, the propeller will work at full fine position. In multi-engine, it is completely opposite, oil pressure increases the RPM(fine), nitrogen gas/spring decreases the RPM(Coarse/feather). So in case of engine failure in a multi-engine aircraft, the pilot can feather the bad engine to decrease drag.

This is a great animation, except one thing that make me confused. For PA44-180, when aircraft overspeed, oil leaves the prob hub and make pitch angle increases and vice versa. This is seems opposite animation in this video. Is there the general concept for all aircraft's CSU, or it differ aircraft by aircraft. Btw, that a great animation.

Hi could you please explain at the beginning of the video (1:30) it says as engine RPM increases(small blade angle) the fly weights move OUTWARDS and as the engine RPM decreases(large blade ) the flyweight move INWARDS , later on in the videos(3:45) it says as to maintain the high RPM (small blade angle) the flyweights now move INWARDS and to maintain a low RPM the flyweights now move OUTWARDS, which is contradicting what was said in the beginning of the video. Could you kindly provide some clarity? Thanks

why is it that in a free turbine when the plane shuts down (less RPM) the prop feathers (pitch increases)? wouldn`t the oil lines have to be swapped and the propeller adjust pitch the other way around?
@XPoChangLinX3 жыл бұрын
They're depicting a single engine aircraft where the engine is designed to windmill when oil pressure is lost. Most multies are designed to feather when oil pressure is lost. Direct drive turbines like most multi pistons have a locking pin that drops in place to prevent the props from feathering when RPM is too low.

Isn’t this something that could be used in human sized quadcopter? How energy efficient is it?
@samcoder6900 Жыл бұрын
Thanks a lot for the great work but if I may, I think the explanation is fundamentally misleading by confusing variable pitch propellers and constant speed ones. It is true that CSU achieve their goal by varying blade angle but the goal of a CSU is first and foremost to keep the engine running at a fairly constant RPM (like a gearbox) , the aerodynamically phenomena on the propeller being the mean rather than the end goal. So saying that CSU are the answer to fixed pitch propellers not having an optimal AoA in most phases of flight isn't correct: variable pitch propellers without a CSU do exist and are a solution to that problem. The philosophy behind CSU has more to do with engine power and efficiency. It is indeed a complex topic and comments and suggestions are welcome.

If the airplane ascending it must increase speed to prevent stall so the blades must be increase angle to take a huge bite of air so the engine must increase the torque.. and opposite is right descending .. not as you mention in video!
@michaelgeorge30923 жыл бұрын
kinda following your thinking. as it climbs, prop loading slows engine rpm, this in turn causes gov to reduce pitch to maintain rpm. but you have less bite, less thrust. only way to maintain thrust is to increase power. right ?
